v IPIhe arm'nrest parttl6-t is similarly.:constructed and/has a. raisedrear poz'ftion.1'6'.and foot members-37. and 38 serving to support the.arm rest.member when .in an upright position andtassembled. Thelinnerwalllboard of- .the'rsiderest member 16 also has transverselyextendiugboardlbra'ckets .guide tracks for the bed members and a togglbr acketforvthe' back rest. .The-bottonibracelboarid 17 is connected by means ofscrews between angle brackets 41 and 42 extending along the lower edgesof the respective side arm parts and 16, Fig. 10.

The transverse brace board 13 is secured by screws between anglebrackets 43 and -34 secured respectively to the respective arm restparts 15 and 16. The transverse back board 19 is connected between anglebrackets 45 and 46 on the respective arm rest parts 15 and 16. Thesetransverse boards are all fastened by screws to the angle brackets andserve to hold the arm rest parts against lateral displacement and tomaintain the form of the sofa. On the upwardly extending rear portions15 and 16' of the arm rest parts are respective brackets 47, only onebeing shown to support the top board 20 to which the back rest is hingedby hinges 48.

The bed spring member 23 comprises a front frame piece 50 to theopposite ends of which there is connected respectively end frame members51 and 52. Between the end frame members 51 and 52 there extend bedspring members 53 having their ends connected by tension springs 54 tothe end frame members 51 and 52. Depending from the front frame member50 and at the respective opposite ends thereof are respective legs 55and 56 having respectively Wheels 57 and 58 adapted to roll over thefloor as the bed is withdrawn or retracted. The rollers or wheels 57 arejournalled respectively upon axles 59 and 60 extending through the lowerends of the legs 55 and 56 and through depending brackets 61 and 62respectively associated with the respective legs 55 and 56. These wheels57 and 58 preferably have rubber tires 63.

At the rear of the bed spring member 23 is a transversely extending pipe64. The ends of this pipe are connected to the lower ends of dependingbrackets respectively connected to the end frame pieces 51 and 52. Thepipe 64 is braced with the respective brackets 65 by diagonallyextending braces 66, Fig. 7. It will be seen that the pipe 64 whichconnects with the bed spring member end frame pieces 51 and 52 isdropped to a location where it will not interfere with the user of thebed. The bed spring member 23 is thus made rigid without the rear framemember 64 being in the way.

The bed spring member 22 is similarly constructed and comprises endframe members between which are connected a plurality of bed springassemblies 71 and a rear angle frame member 72, Fig. 7. The respectiveend frame members 70 of the bed spring member 22 are respectivelyconnected by hinges 73 with the respective end frame members 51 and 52of the bed spring member 23.

Pivoted respectively to the respective forward ends of the frame members70 of the bed spring member 22 are pivotal brackets 74 between the lowerends of which are rigidly connected a dropped frame pipe piece 75,serving to brace the front of the bed spring member 22. It will thus beseen that by this means the brace pipe 75 will be retained out of theway of the user of the bed. Connecting links 76 respectively connecttogether the brackets 65 and 74 whereby to retain the pivotal brackets74 in vertical parallel positions and the frame pipe 75 always under thebed spring member 22.

It will now be seen that the bed spring members 22 and 23 are hingedlyconnected together and that the bed spring member 22 can be hingedupwardly so as to be located in the back of the sofa but which will beautomatically hinged downwardly as the bed spring members are pulledoutwardly of the sofa parts. It will be clear now that the bed springmember frame pipes 64 and 75 will always be in a position such that nocross bars or pipes will interfere with the full spring action of thebed and that the spring assemblies are free of the frame pipes andadapted for comfortable sleep.

Extending inwardly from the arm rest parts 15 and 16 are respectivebrackets 77 and 78 adapted to underlie respectively lugs 79 and 80weldingly secured to the respective front legs 55 and 56 of the bedspring member 4 23. Upon lifting the ends of the combined sofa and bedthe brackets 77 and 78 will engage with the respective lugs 79 and 80 sothat the front edge of the bed spring member 23 will be supported as thearm rest parts are lifted whereby to keep the bed spring members fromdropping downwardly on to transverse brace board 17.

On the respective end pieces 51 and 52 of the bed spring member 23 arerespectively guide rollers 82 adapted to travel respectively over guidetracks 83 and 84 secured to the inner boards of the respective arm restparts 15 and 16. The ends of the guide track 83 are turned down asindicated respectively at 85 and 86, Fig. 7. The ends guide track 84 arerespectively turned down as indicated at 87 and 88. With the rollers 82resting on the turned down ends 85 and 87, the bed spring members willbe locked against outward movement from the sofa parts. Upon the rollers82 being rolled down over the forward bent ends 86 and 88, the bedspring members will be held in their outwardly extended positions andagainst the rearward pull of a counterbalancing spring mechanismindicated generally at 90 and mounted on transverse brace board 18.

The counterbalancing mechanism comprises a heavy tension spring 91 whichis anchored to a bracket 92 mounted on the front face of the board 18. Adouble pulley bracket 93 having pulleys 94 and 95 is mounted on the endof the board 18 adjacent the arm rest part 15, Fig. 10, and on theopposite end of the board 18 adjacent the arm rest member 16 is a singlepulley bracket 96 having a pulley 97. A cable of wire rope 98 has itsrespective ends run through the respective pulleys 95 and 96 forconnection with wheel axles 59 and 60 on the legs 55 and 56 of the bedspring member 23. The wire rope cable is doubled on itself and extendedover pulley 94 and connected to the free end of heavy tension spring 91in the manner as indicated at 99. With the counterbalancing mechanismarranged in this manner, an equal pull will be effected upon theopposite ends of the front bed spring member 23. The rollers 82 will beheld against depending ends 86 and 88 of the side tracks 83 and 84 bythe spring tension of the counterbalancing mechanism 90 and in order torelieve the front bed spring member 23, a slight pressure will berequired to start the rollers 32 upwardly over the bent ends 86 and 88.

On the rear end of the bed spring member 22 are guide roller bracketswhich are upstanding 100, disposed respectively on the opposite framepieces 70 and having respectively guide rollers 101. Extending in aninclined manner on the respective arm rest parts 15 and 16 and over therear upstanding portions 15 and 16' thereof are respectively guidetracks 102 over which the guide rollers 101 will run. As the bed springmembers are drawn outwardly, the guide roller 101 will roll down theguide track 182, Fig. 7, and will finally come into engagement with aguide bracket stop 183 located at the lower end of the guide track 182and secured to the arm rest part. So that the bed spring member 22 willremain in a position for use as a bed part, there is a guide track 102and a stop bracket 103 on each arm rest part.

The depending back rest 21 comprises a frame 105, Fig. 3, between theends of which there are extended a plurality of spring assemblies 196having tension springs 107 against which a cushion 108 may be pressed.In order to permit the back rest to be elevated, the same is hinged tothe top plate or brace 20 and is held in either its lifted or loweredpositions by an over-center toggle bracket mechanisms 168' secured tothe opposite ends of the back rest 21 and connected respectively to thearm rest parts 15 and 16. Each of the over-center toggle bracketscomprise an attaching member 109 that is fixed by screws 110, Figs. 3and 4, to the arm rest part. The upper end of the attaching member hasan inwardly bent end 111. The lower end of the attaching member 109 hasa pivot pin 112 with a toggle link 113 pivotally con nected thereto. Atoggle link 11-5 and a pull link 115 are pivotally connected to thetoggle link 113 by a pivotal pin 116. The toggle link 114 is pivotallyconnected by a pin 117 to a bracket 118 that is fixed to the end of theback rest frame 105. The pull link 115 is connected by a tension spring119 to the inwardly bent end 111 of the attaching member 109 to exert anover-center pressure upon the toggle pin 116 and the toggle links 113and 114. On the respective arm rest parts and 16 are stop brackets 120serving to prevent the back rest from outward movement beyond a positionadequate enough to free the bed spring member and mattress from the backof the furniture piece. The pull link 115 will abut the stop bracket 120to thereby limit the outward movement of the toggle mechanism and theback rest beyond its forward position. After the mattress 26 and the bedspring members 23 and 22 have been pulled out, the back rest 21 can belowered to its original vertical position and the fabric cover 28brought forwardly, as shown in Fig. 6, over the front board 27. Thisfabric can be folded under the bed when the bed is in use and thereafterwhen the mattress and bed spring members are returned by a slight push,as illustrated in Fig. 5, into the sofa parts. The back rest would bepulled out prior to this return of the mattress and bed spring members.The front board 27 is preferably cushioned and covered with fabric, asshown in the sectional views. A slight pres sure on the front board 27causes the rollers 82 to ride up over the downwardly bend ends 86 and 88of the respective to ride up over the downwardly bent ends 96 and 88 ofthe respective tracks 83 and 84 and the counterbalancing springmechanism will automatically return the mattress and the bed springmembers to their retracted positions within the sofa parts.

It will now be apparent that there has been provided a combined sofa andbed which has the simplest form of operationto convert the sofa into afull size bed or a full size bed to a sofa.

It shall also be apparent that the mattress will not have to becompletely doubled up when stored in the sofa parts so that wear andtear upon the mattress is minimized.

It should also be apparent that the bed is so constructed that theadjacent frame pieces of the respective bed spring members are loweredso as to permit free and full spring action of the entire bed area. Bymerely detaching th; screws which hold the brace boards to the bracketsof the arm rest members the furniture piece can be disassembled to allowits parts to be stored or the piece taken through a small-doorway.

While various changes may be made in the detail construction, it shallbe understood that such changes shall be within the spirit and scope ofthe present invention as defined by the appended claims.
